Major Mines & Projects Tucano Mine
Open pit Mineral Reserves are estimated within designed pits above discard cut-off grades that vary from 0.43 g/t Au to 0.5, g/t Au for oxide ore and 0.58 g/t Au to 0.63 g/t Au for fresh ore. Underground Mineral Reserves were estimated using an incremental cut-off grade of 2.4 g/t Au
Operations Minera San Cristóbal S.A.
This means that it moves a daily average of 150,000 tons of rock, 52,000 tons of which go to the concentration plant for treatment. The concentration plant consists of a primary crusher, a 1.7 kilometer-long conveyor belt, a giant dome for dust suppression, a milling circuit with a SAG (semi-autogenous) mill, two ball mills, cyclone banks for the re-circulation of the load, a differential
Innovations: How Do They Do That? How Copper is Made
Copper ore, in concentrations ranging from 0.29 percent to ten times that amount, is mined from open pit or underground mines. The crushed mine ore is ground in rod and ball mills and then sent to flotation machines where the copper mineral rises to the top in a froth, making a copper concentrate of approximately 30 percent, 27 percent iron and 33 percent sulfur.
Molycorp/Mountain Pass Mine & Mill Site/WDR's
It operates an open pit mine on 2,223 acres near Interstate 15 in the community of Mountain Pass. The mine extracts and processes ore containing lanthanide (rare earth) elements, primarily the mineral Bastnaesite. The processing procedure sends the ore through an ore crushing plant, ball mill, flotation plant, and acid leach plant.
